Title: Tatung monitor - no vertical Post by: badbaud on March 09, 2009, 01:34:02 AM This monitor has no vertical - just a horz. line. Replaced all caps and LA7836 vert driver, no help. Disconnected yoke but still no output on LA7836. Power supply putting out
proper +24 and +110. Vert yoke coil reads 4 Ohms. LA7838 has 12VDC Vcc and vert sync pulses are present on input. Hampered because I can't find a schematic for this particular model. This one has a separate switching power supply mounted to the chassis. Number on PC board is C920R-01. Where can I get a schematic or any suggestions on how to get vertical to work? |
